With regards to TASM'SAcceptable Complex Expressions.... I'd like to ask about the following:

mov cx, (2+3)[bx](2+3)*[2]

This expression is accepted by TASM 3.1 and is compiled into MOV CX, [BX+19]

What is weird is that, when I add another register i.e. [SI], wherever I place it there becomes an error. There is no problem with + and - operations, but there is some ambiguity with * and / causes an error.

I know quite possibly that it would be rare that people would program using these kinds of complex expressions, but because I am building an interpreter that is for our thesis, I just could not get into the actual semantics that concern these kinds of expressions.

If ever you can help me with this or refer me to a good book or what. Please email me at freon_r22@yahoo.co.jp.  Thanks so much. :)
